To all whom it may concern:

Be it known that I, WILLIAM A. -HARD- WICK, a citizen of the United States, residing at Memphis, in the countyof Shelby and State of Tennessee, have invented a new and useful Cut-OE for Barrel-Filling De vices, of which the following is a specification.

This invention has reference to improvements in barrel filling devices and its object is to provide a structure which will cut off the flow of liquid into barrels or other containers when the proper level therein barrel filling and cut-off device.

has been attained. 1

In the present invention a valve is provided between a source of supply and the barrel or other container, in a conduit for the fluid, and this valve when opened is held in the open position against the force tending to close it, the means for maintaining the valve open consisting of a suitable latch. When the fluid level has been reached at which point it is desired to cut off the How of liquid, then the rise in the fluid level causes the operation of the latch in a manner to release the valve to the force tending to close it, so that further flow of liquid into the barrel or container is arrested.

The invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawings forming a part of this specification, in which drawings,

Figure 1 is an elevation partly in section and partly broken away of the improved Fig. 2 is a detail section of a portion of the mounting for the valve stem. Fig. 8 is a view partly in section showing the application of the filling device to ice-machine cans. I

In the present device practically all the parts are stock parts and may be bought in the open market so that initially the device may be constructed at small cost, and parts which must be manufactured specially are avoided. Therefore, the initial cost of the device is small and repairs may be readily made by the owner with parts purchasable from any dealer in fittings for water or steam pipes.

Referring to the drawings there is shown a connection 1 in the form of a T hereinafter referred to as the secondary T, the T comprising a shank and a head 51, the head recelving at one end a pipe 2 constitutmg a float casing and having at an intermedlate point an interior web 3 which though shown in the drawings as in one piece with the pipe may readily be made separate therefrom. The pipe 2 is provided adjacent to the T1 with external screw threads as indicated at 1 to receive a spider 5 designed to engage the outer surface of the barrel when the pipe 2 is introduced into the barrel through 'a bung-hole. The degree of entrance of the pipe 2 into the barrel is determined by the position of the spider 5 which may be screwed along the pipe 2 to any desired point within the range of the screw threads 4'. Above the web 3 the pipe 4 is provided with openings 6 for the passage of fluid from the T 1 to the interior of the barrel when the pipe 2 is introduced therein. Rising from the web 3 is a tube or' pipe 7 which may at the lower end be screwed into the web and this tube extends through the T into a cap 8 at the other end of the T. Extending through the tube 7 is a rod 9 passing into the pipe 2 below which the pipe 2 constitutes a casing. This rod extends beyond the'cap 8 and is screwed into a yoke block 11 to which it may be secured in any position of adjustment by the lock nut 12. Rising from the T l is a post 13 to the upper end of which is pivoted a lever 14; connected at one end to the yoke block 11 and at the other end provided with a tooth l5. Screwed into the stem end of the T 1 is a nipple'16 receiving at the otherend one end of a valve casing 17 and this valve casing in turn is coupled to a pipe 18 'which may lead to a suitable source of liquid tamers. The valve casing 17 receives on one side a removable plug 19 and within the valve-casing 17 there is a flap valve 20 provided with a stem 21 one end of which extends through a packing gland 22, and exterior thereto has secured to it an arm 23 provided at the outer end with a pin 24 adapted to engage behind the tooth 15 of the lever 14. The valve 20 is under the normal control of a spring 25' connected at one end to the arm 23'and at the other end to the casing 17, this spring tending to move the valve 20 to the closed position. Secured to theT 1 is a handle 26 for the ready manipulation ment of the tooth 15 with the pin 24 of the valve arm 23, the weight of the float 10 being sufficient to maintain the parts in this position. Liquid will flow through the pipe 18 thence to the valve casing 17 and through the nipple 16 into the T 1 and thence by way of the pipe 2 andto the interior of the barrel through the opening 6 in said pipe.

The valve 2O is a flap valve and when open the flow of liquid through the valve casing 17 is practically unimpeded and the liquid may therefore flow to the barrel with the same freedom as though the valve were not present. When however, the desired liquid level has been reached within the valve then the float 10 is lifted and the toothed end of the lever 14 depressed, thus releasing the arm 23 and the valve 20 is moved to the closed position by the action of the spring 25 augmented by the pressure of the liquid.

I'Fwill be observed that the valve stem 21 does not move longitudinally through the packing but only rotates therein so that leakage of the liquid is prevented for the wear on the packing is ne ligible.

In Fig. 3 there is s own a structure especially adapted for the filling of ice machine cans, one of which is indicated at 27 in the said figure. In general, the parts of the device are the same as already described with relation to Figs. 1 and 2, but in place of the nipple 16 there is introduced another primary T 28 and between the head 52 of this T and the shank 23 of the secondary T 1' there is a solid plug 29 so that there is no communication between the T 28 and the T 1. Connected to the shank 54 of the T 28 is a pipe 30 of such length as to reach to the bottom of the can 27 and there this pipe is provided with openings 31 or any other means of escape for the liquid passing through the pipe.

In order to prevent entrance of liquid into the pipe 2', which constitutes a casing and is mounted in one end of the head 55 of the secondary T, the openings 6 are omitted in the structure of Fig. 3 but otherwise the pipe 2 is the same as shown in Fig. 1.

The-structure may be centered in the can by means of diverging arms 32 designed to engage the inner faces of the can, and these cans, as usually employed in ice-machines, are rectangular in cross section. The arms 32 may be arranged to engage the corners of the can and thus support the device in centralized position in the can without dancasing constitutin ger of displacement during the filling of the can. At the same time such structure does not prevent the ready removal of the filling device from the can after the latter has been filled.

Because of the solid plug 29 no liquid passing pipe 2 or the T 1 but all the liquid will flow through the T 28 into the pipe 30 and so into the can 27. In Fig. 3, the pipe 2 obviously constitutes a casing for the float 1.0. The pin 24 and the tooth 15 constitute interlocking elements, adapted to engage when the arm 23 and the lever 14 are properly positioned with respect to each other. Owing to the fact that the valve casing 17 is rotatable upon the pipe 16, the arm 23 may be adjusted with respect to the lever 14, so that the tooth 15 will engage properly with the pin 24. Moreover, because the rod 9 is threaded into the yoke block 11, the float 10 may be adjusted with respect to the web 3, so that when the float 10 is raised, into abutment with the web 8, the pin 24 will be moved out of engagement with the tooth 15. It will be seen, therefore, that by rotating the valve casing 17 upon the pipe 16, the pin 24 and the tooth 15 may be positioned for engagement with each other; and by rotating the rod 9 in the yoke block 11, the float 10 will be so positioned with respect to the web 3 that the raising of the float 10 will with certainty break the interlocking relation between the pin 24, and the tooth 15.
